本文详细介绍如何使用IDEA及Maven快速搭建SSM框架，包括项目创建、依赖包引入及配置文件设置，并提供了一个简单示例。

搭建步骤

众所周知，基于IDEA开发的项目越来越多，IDEA的发展也已经势不可挡，今天，我就来教大家使用IDEA搭建一个完整的SSM框架

一、IDEA创建项目

new——project

我们选择maven


图中红色部分必须勾选，然后创建名，可以随自己爱好创建，比如我的是ssm


注意此时这个位置我们必须选图中的位置，如下图：




等新界面出现后，我们需要点击Import changes，另外一个不用管。


此时呢我们看到的这个界面就是搭建好了前提环境条件



二、SSM框架所需要的类包



图中的pom.xml文件你可以理解为Maven作用。IDEA方便就在此，在我们导入以下文件后，就可以自动下载依赖包，非常方便。




<dependencies>
  <!-- 添加jstl依赖 -->
  <dependency>
    <groupId>jstl</groupId>

    <version>RELEASE</version>
  </dependency>

</dependencies>


导入过后，IDEA会自动提示你Import changes，我们点击，然后会显示它正在导入包，等它结束我们就导入好了。





三、配置文件


经过第二步，我们SSM框架所需的包都已导入，接下来我们配置文件。


web.xml文件内容







<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">

    <display-name>web-ssm</display-name>
    
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mybatis.xml</param-value>
    </context-param>

    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>

    <!-- 编码过滤器 -->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 防止spring内存溢出监听器，比如quartz -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>


    <!-- spring mvc servlet-->
    <servlet>
        <servlet-name>SpringMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
        <async-supported>true</async-supported>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringMVC</servlet-name>
        <!-- 此处也可以配置成 *.do 形式 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>
    </welcome-file-list>

    <!-- session配置 -->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

</web-app>


然后我们在main下resources下创建jdbc.properties    log4j.properties    spring-mvc.xml    spring-mybatis.xml    四个文件，再在main下创建mapping包，mapping包下在创建UserMapper.xml映射文件





jdbc.properties内容如下，我们只要把username和password改成自己数据库的用户名和密码就行了




driverClasss=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true&useSSL=false
username=root
password=122015

log4j.properties内容如下





log4j.rootLogger=INFO,Console,File


log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n


log4j.appender.File=org.apache.log4j.RollingFileAppender
log4j.appender.File.File=logs/ssm.log
log4j.appender.File.MaxFileSize=10MB

log4j.appender.File.Threshold=ALL
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n



springmvc.xml内容如下：




<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!-- 自动扫描  @Controller-->

    <!--避免IE执行AJAX时，返回JSON出现下载文件 -->
    <bean id="mappingJacksonHttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>
    <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
   <mvc:annotation-driven/>
    <mvc:default-servlet-handler/>


    <!-- 定义跳转的文件的前后缀 ，视图模式配置 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />

        <!-- 内存中的最大值 -->
        <property name="maxInMemorySize" value="4096"/>
    </bean>



</beans>


spring-mybatis.xml内容如下：

        <property name="fileEncoding" value="UTF-8"/>
    </bean>
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">
        <property name="properties" ref="configProperties"/>
    </bean>
    -->

    <!-- 配置数据源 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
          destroy-method="close">
        <property name="driverClassName" value="${driverClasss}"/>
        <property name="url" value="${jdbcUrl}"/>
        <property name="username" value="${username}"/>

    </bean>

    <!-- mybatis和spring完美整合，不需要mybatis的配置映射文件 -->

    <tx:annotation-driven transaction-manager="transactionManager"/>


</beans>



此时我们的SSM框架就搭建好了。
